Gasometer Dietrich Fruling

Gasometer Dietrich Fruling used for the determination of CaCO3 especially in limestone and lime marl. It consists of a glass container in which the reaction between the calcium carbonate contained in the products and a solution of hydrochloric acid takes place. The gas given off is collected with the container. Being measured the volume of gas (CO2) given off it can be related with the quantity of CaCO3 contained in the sample.
